CONNECT MANAGE

11.
● CoAP
○ « HTTP over UDP »
○ Expose your device as a resource on the Internet of
Things
● MQTT
○ Publish/Subscribe model
○ TCP-based
Connecting things to the IoT

12.
CoAP - RFC 7252
● RESTful protocol designed from scratch
○ URIs, Internet Media Types
○ GET, POST, PUT, DELETE
● Transparent mapping to HTTP
● Additional features for M2M scenarios
○ e.g Observe
